Corrostop
Corrostop is the only known cure for Cosmic Rust. It is a clear blue liquid, which can be applied to a surface by pouring or spraying.
Fiction
The Transformers cartoon
Perceptor created the substance for the purpose of removing and preventing corrosion of any form. The Autobots used their initial batch to coat the Statue of Liberty. While the work was underway, the Stunticons kidnapped Perceptor and took him to Decepticon Headquarters, where he was compelled to help cure Megatron of a Cosmic Rust infection. It turned out corrostop was just as effective on Cosmic Rust as it was on normal rust, and a small sample beaker that Perceptor had on his person proved to be enough to cure Megatron and any other affected Decepticons.
Unfortunately, after the initial batch was exhausted, Cosmos and Blaster discovered that the supply of the key ingredient, Ingredient X, had been completely used up and could no longer be found anywhere. Fortunately, after Megatron attempted to spread the Cosmic Rust amongst the Autobots, they were still able to use a matter duplicator to create a large enough supply from scrapings off the Statue of Liberty to cure everyone who was infected.

When Oil Slick got infected with and disabled by his own Cosmic Rust, he tricked a young Ratchet into synthesizing and applying his antidote formula for him. Oil Slick then turned around and infected Ratchet before escaping, but Ratchet was able to steal some of the antidote and use it on himself as the Decepticon sped away. He then brought it back to the Autobots to be mass-produced as corrostop. 'Bots of Science The AllSpark Almanac
